The surroundings of the laboratory building were surprisingly quiet, and the occasional sound of unknown insects and birds could be heard around them, which also broke the silence of the night, and even such an insignificant sound sounded terrifying at ......this time.

However, for Xiaolong and Dong Ming, they didn't have the extra heart to listen, and the two were trapped in the corridor on the third floor of Building B, and they were attacked on their backs.

"Roar."

A cool breeze mixed with the stench of blood hit behind him, waking up the two who were hesitant, Dong Ming immediately decided to break through from the relatively weak monster in front of him, and said.

"This aunt doesn't look that tough, we rushed over from here, you fainted, followed me, grabbed the gap and ran over."

Looking around, there was a broom resting next to the door, which had been placed there by the previous cleaners. Zhou Peng, who was behind the two, was about to catch up with him, so he couldn't think about it anymore, Dong Ming held it tightly in his hand, and rushed towards the cleaning with Xiaolong one after the other.

The sound of hurried footsteps immediately alerted the cleaning monster in front of him, and his twisted body was slowly moving towards the middle of the corridor, and the black blood that kept flowing from the corners of his mouth was already on the ground.

"Howl."

Sure enough, this time she could only rush over by pushing her away, Dong Ming held the top end of the broom, and the other end pressed against the chest of the cleaning monster.

"It's quite strong, get out of here." While Dong Ming scolded secretly, the strength in his hand continued to move forward, but he didn't see it retreat, and Zhou Peng followed closely behind him, he didn't want to face the big man of one meter eight compared to him.

"Help, Xiaolong." Dong Ming begged for help, but after he finished speaking, he felt that he was doing too much, because the strong smell of blood had made Xiaolong dizzy again, and he was holding on to the wall, struggling to walk, let alone helping himself.

Dong Ming, who was helpless, could only rely on himself, grabbed the end of the broom with one hand, and then kicked it in the chest, this kick forcibly pulled out the broom stick, and then looked at the broom head, and was actually kicked into the clean flesh by Dong Ming and pierced into the blood vessels.

The wooden stick is in his hand, one end is a little sharp, held horizontally in his hand, and the threat behind him is pressing, and in a hurry, he uses the stick as a sword and suddenly stabs it into the chest.

"Poof."

Dong Ming was shocked, he didn't expect that his stick would directly stab into the body of the cleaner, and he was a little dazed for a while, looking at the wooden stick that came out of his body, and the black blood fell drop by drop on the wooden stick that exposed half of the body behind him.

The silence for a moment made people's hearts furious, and a drop of black blood hit the smooth floor tiles heavily, as if it opened a nerve in Dong Ming's heart.

"I killed, I killed, I'm sorry, I'm sorry." Dong Ming said in a panic, but his hands and feet were as clean and neat, and he couldn't tell that he was killing someone for the first time.

Dong Ming saw the monster in front of him with a bloody face, with a wooden stick of more than a meter stuck in his chest, and it was slowly falling, and the blood flowed like a pour, staining a large area of red where she was.

"Roar."

The sound of the cleaning was much quieter, but it was still struggling on the blood-soaked floor tiles, and a pair of blood-stained hands were slowly crawling towards the two of them, dragging a long blood mark on the ground.

Seeing this, Dong Ming immediately said calmly.

"Run, little dragon."

Holding Xiaolong beside him, he rushed along the wall, and caught a glimpse of the cleaning aunt who was still struggling, and Zhou Peng, who was chasing after him, had also arrived at the place where he had just stayed.

But fortunately, at this time, the two of them were already walking in the stairwell, desperately running downstairs.

The yellowing light hit Zhou Peng's blood-red eyes, and his thick body became even more ruthless against the background of the dark corridor, Xiaolong gradually regained some strength, and looked up behind him, that scene was deeply imprinted in his mind from then on.

Zhou Peng's slightly clumsy footsteps, one foot on the body of the cleaner, both hands groped to grasp the still struggling body of the cleaner, two big hands grabbed his neck with one hand, grabbed his thigh with the other, and pulled hard, only the sound of flesh and bone separation, internal organs tearing.

"Whew."

Flesh and blood were flying, blood was splashed everywhere, Zhou Peng stiffly divided the cleaning body into two, only the one was left at both ends, even so, the cleaning woman's hands were still waving wildly, the roar in her mouth gradually decreased, and the strong smell of blood continued to stimulate Zhou Peng's nasal cavity.

Zhou Peng bit the tear off, directly bit off a large mouthful of flesh and blood, kept putting it in his mouth and chewing, making a sizzling sound, and then sucked the red on his thigh.

"Knock, knock."

This sound of drinking water is the sound of Zhou Peng drinking blood, but it sounds so terrible in the current environment, with Zhou Peng's sucking, the cleaning finally has no movement, and the red bloody eyes have turned white again from red, but this time they are all white, without any blood, and the body has withered down.

"Roar."

Zhou Peng roared, breaking the silence of the entire laboratory building again. At this time, Dong Ming and Xiaolong almost ran to the first floor and quickly walked through the hall.

"Wait, close the door to the hall and notify the school immediately." Xiaolong suggested.

"Okay, okay, hurry, you go and inform, I'll go back to the dormitory and pack my things." Dong Ming and Xiaolong said as they ran.

"What are you doing packing up?"

"Didn't you see, I killed someone, I killed Aunt Cleaning, I can't stay here anymore, I can run as far as I can, maybe I will have a chance to escape ....., you ...... You won't betray me, will you? Dong Ming suddenly asked.

"Don't worry, at most, this is your legitimate defense, and when I just went downstairs, I saw that it was Zhou Peng who really killed the cleaning aunt, and I saw with my own eyes that it was his ......." Recalling the picture just now, another wave of dizziness struck, and the little dragon, who slowed down, also stopped describing in his mouth.

"Just in self-defense?"

"Yes, through the observation just now, it is obvious that Aunt Jie and Professor Zhou are both infected, and it is preliminarily concluded that they should have been exposed to some kind of rabies virus-like agent, which caused the mutation of the two, as long as we notify the school in time and isolate them, there will be no more casualties."

"Did you close the door just now?"

"It's off."

The two were about to rest assured, Xiaolong suddenly stopped, stunned in place, Dong Ming was puzzled and asked, "What's wrong?" ”

"We only closed the door of Building B, and I don't know if the other doors were closed."

"It should be closed... Right?" Dong Ming replied, but there was a question in his tone.

"No, I'm going to go back and check it out."

Dong Ming hurriedly grabbed Xiaolong and said, "No, we finally ran out, what if we go back now and run into infected people again?" ”
